An upwardly open wallpaper wetting trough made from flexible polystyrene has a metal rod force fitted between the opposite ends of the trough and has vinyl tips fitted over the rod ends to protect the ends of the trough from puncture. An inwardly opening, outwardly extending channel is formed in each end of the trough to receive the ends of the rod in a force fit to maintain the rod in position while a sheet of wallpaper is being pulled through water in the trough guided by the rod.
